Projectile Motion

Projectile motion is a form of motion where an object or projectile is thrown into the air. There is 3 parts of projectile motion, Angle of release, height of release and speed of release. The angle of release is the the optimal AoR can vary, the average angle release is 45 degrees but in so activity like shot put there average angle release is 32-38 degrees. Height of release is the higher the release the longer and object will travel. The Speed of release is the greater the speed, greater the height and distance the object travels. The activity we did was a rubber band activity were we had to flick the paper in the air. We had to figure out the right amount of paper to use for the paper to travel, We had to figure out how to make create the most speed to make the paper travel more further and the angle to release the paper so it can travel longer.

Levers

Today we did an activity about levers, a lever is made up of three parts effort, Load/resistance and fulcrum.

The fulcrum is like the pivot point of the lever, the effort is the forces applied and the Load is the thing that needs effort to be applied.

There are 3 classes,

 class 1 a example is an seesaw

 class 2 a example is an wheelbarrow

 class 3 a example is an arm

Lever I are used a lot in sports for example badminton, When you hit the shuttlecock with the racket your fulcrum is your hand, the efforts is your muscles in your arm used to swing the racket and the shuttlecock is the load.

In the activity we did we had to cut out and colour in shapes and had to label them, the green was effort the yellow was fulcrum and the purple was the load. We then had to shape them into each of the classes and then we had to explain why it was that class.

Zumba reflection

• Explain the physical activity you participated in. Today we participated in an activity called Zumba. Zumba is sort of an work out to get you pump up and relax you body, It is like a dance and you can try and dance to any song you want.
• What level of effort and engagement were you participating at during today’s physical activity? Why? (Grade yourself NA, A or M and refer to marking criteria) I would give myself an achieved because I was prepared and organised and brought my gear. I also tried to improve my skills by following the dance moves on the screen and demonstrated my skills by showing my accurate dance moves.
• What were three factors which influenced your participation? (Choose from the list below, and put a + or - beside the three factors to show whether it positively or negatively influenced your participation). -Well-being -friends/classmates -Previous
• Explain HOW these factors affected your participation (with specific examples) Well-being affected my participation in negative way because we just came back from the holidays so I was still tired and it made me not want to join in. Friends/classmates affected me in negative way because I would sometime see them not dancing and sitting down so it made me want stop and sit down and made me not want to participation. previous experience affected me in a negative way because I didn't know what zumba was then my teacher said it was like dancing and made me not want to do it.
• How could you increase your (or your peers) participation in this activity in the future? I think I could increase my participation by getting more involved with the activity and try and get my friends to try and participate and more energised.

Badminton reflection

• Explain the physical activity you participated in. The activity we played today was badminton, we had a team of two and played around 5 minutes for each opponent before we rotated. If you don't know what badminton is it is similar to tennis where you have to try and hit the ball over the net, but in badminton you have to use an different racket and the thing you hit was an shuttlecock.
• What level of effort and engagement were you participating at during today’s physical activity? Why? (Grade yourself NA, A or M and refer to marking criteria) If I had to grade myself today I would have given myself an merit. I gave myself an merit because I would always motivate my teammate kori by cheering him on every time he got a point. I would also give myself an merit because I help my teammate a lot by showing him to hit the shuttlecock.
• What were three factors which influenced your participation? (Choose from the list below, and put a + or - beside the three factors to show whether it positively or negatively influenced your participation). +Friends/teammate +previous experience - equipment
• Explain HOW these factors affected your participation (with specific examples) Friends/teammates affected my participation in a positive way because my teammate was my friend kori and we would always hype each other up so it made me want to play more. Previous experience affected my participation in a positive way because I never played badminton before so it me more eager to play. Equipment affected my participation in a negative way because so of the nets were broken and the shuttlecocks were broken so it would someones go off to somewhere else which made want to play less
• How could you increase your (or your peers) participation in this activity in the future? To increase my participation I think that I need to try and learn how to play more so that I can get better and help my teammate out more and show him things so that I can help him improve.

Force Summation

What is Force summation? Force summation is made up of 3 parts, but the all together is means adding forces together to create the greatest force as possible.

Describe the three parts of force summation? The three parts of force summation are range of motion, order of body segments and timing of body segments.

Range of motion is the greater the range of motion the greater force produced. 

Order of body segments is when forces is transferred from the largest muscles, through to the smallest muscles. 

Lastly is timing of body segments is when each body segment should be activated when the one before it has reached its peak.

Describe the activity we completed in the gym and how this related to force summation? 

The activity we did in the gym was on the rowing machine we were giving a task to go step by step for a full row. We went from only using only our hand to using our full body. This activity showed us that the more motion we use it will generate more force. This activity used all parts of force summation like order of body segments, if you want to produce the greatest force we had to start from you legs and all the way up to your arms. if I started from somewhere else it wouldn't be the same.
